10 Claims.

vvide individual suction means arranged close to each bobbin, and adjustable to follow the roving or yarn as the size of the wound roving decreases.

A further object of the invention is to provide means for collecting and holding the dirt or lint which has been removed from the roving or yarn, and which is so constructed that parts thereof may be removed for cleaning or repair. A further object of the invention is to provide a vacuum tank as a source of suction, which tank also serves as a support for the skewers and the-pipes carrying the suction nozzle, such tank being mounted upon the top of the spinning frame.

Other objects and advantages of the invention Will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, rthe numeral I0 designates the top of a conventional spinning frame. These spinning frames are ordinarily about 32 to 36 feet in length. I use separate vacuum tanks II, as a -with handles 25.

source of suction for a given number of suction units. I ordinarily employ I6 separate suction tanks II, and these tanks are rigidly mounted upon the top III.

Each tank is preferably rectangular in horizontal cross section -and tapers upwardly, and has upwardly converging sides I2, a bottom I3 vertical ends I4 and a top I5. The top I5 has a large opening I6 forming a ilange I1. A cap I8 covers the opening I6 and is detachably secured to the flange Il by bolts I9, passing through a rubber packing rings 20. These bolts are secured to the ring I1 and carry nuts 2l. The cap I3 has a handle 22, for convenient manipulation. Any other suitable means may be employed to detachably connect the cap I5 with the flange I1, and to form a. vacuum tight joint.

Mounted within the tank II near its longitudinal center is a horizontal strainer-partition 23, which is formed of perforated sheet metal, the apertures being sufliciently ne so that the strainer-partition will catch large particles of lint or the like, This strainer-partition has a central portion 24, Figures 7 and 8, and this central portion is removable and may be equipped The strainer-partition 23 is mounted upon angle irons 26, while the removable central portion rests upon a ring 21 rigidly secured to the outer portion of the strainerpartition and also rests upon an upstanding tube 28, as shown. The central removable portion 24 has an opening 29, as shown. The numeral 30 designates a cylindrical strainer element, including a circular top 3| carrying the tube 28 and an annular bottom 32, which is preferably inclined upwardly toward its center. The top 3I and bottom 32 are connected by an annular group of rods 33, which are spaced. The top and bottom and rods form a rigid cylindrical cage. Surrounding the rods is a side 3l, which may be formed of perforated sheet metal, and surrounding. this perforated side is a wire mesh 35, which mesh is iine and is about a 40 mesh.

Leading into the bottom of each tank Il is a Vertical pipe 36, having a gas tight fit with such bottom, and passing through rubber packing 31 beneath the inclined bottom 32 and an opening 38 in the inclined bottom. The top of the pipe 36 is closed by a head 39, welded or otherwise rigidly secured thereto, and this head has a rod l0 rigidly secured thereto. This rod is vertical and extends through the tube 2,8 and through the opening 29 and carries a'winged nut Il. The upper portion of the pipe 36 has apertures 42, as shown. The pipe 36 cannot move with respect to the 3 tank I I and may be soldered or welded to the bot tom i3. When the nut 4I is screwed up. the central portion 24 ls iorced down against the tubo 2l, and the bottom 32 presses against the rubber packing 31. whereby this packing prevents any leakage between the pipe 33 and bottom I3. When'the nut 4I is removed from the rod 40. the strainer portion 24 is removed from the opening 24', and the strainer unit III may be passed upwardly through the opening 24', the head 33 passing through the opening 36. All of these elements now enter the upper portion of the tank II and may be removed through the opening I6. The pipes 36 have valves 36a connected therein.

The pipes 36 correspond in number and arrangement to the tanks II, and these pipes are connected a common pipe 36'. Figure 1, which leads to a suitable source of vacuum or suction. The pipe 36' has a branch pipe 36h connected therein, equipped with a valve 36e. A ilexible hose 36d is secured to the pipe 36D and may be employed to clean the individual tanks I I.

Each tank I I carriesl skewers 43, which are vertically inclined and extend upwardly toward their free ends. Each skewer 43, Figure 4, has a shank 44, inserted within a sleeve 45. The sleeve 45 has a base 45a, rigidly secured to the tank Ii by screws 46a, welding or the like. Shank 44 is cylindrical and is rotatable within the sleeve and engages at its end a bearing ball 46h. The cylindrical shank 44 is held within a radial ball bearing 46c, the outer race of which has a press lit in an annular groove 46d and the inner race of which has a press fit upon theshank 44. The shank 44, Figure 4a, has a shoulder 46e and radial lugs 4.6f are welded or rigidly secured to this shoulder. These lugs are provided at their ends with grooves Memor urea 8 and 5. carrying radial tubes 55, formed in- 46g for receiving a split resilient ring 46h. Each skewer 43 receives thereon a bobbin 41 having a roving or yarn'48. The lower end 48a of the bobbin has notches 49a to receive the lugs 46j, and the lower end 48a is retained spaced from the sleeve 45. The split resilient ring 46h is carried by the end 48a and .engages within the grooves 46g. The bobbin is-therefore removably mounted upon the skewer 43 and rotates therewith. The roving from the bobbins pass downwardly to the draft rolls and then to the bobbins upon which they are twisted and wound, in the conventional manner. As more clearly shown in Figure 6J the skewers 43 are arranged in spaced horizontal rows and there are three skewers in each row. The skewers in each horizontal row are disposed in staggered relation to the skewers in the next horizontal row. The skewers are also arranged in vertically inclined rows. The skewers are also disposed in upper inclined pairs and lower inclined pairs. These skewers carry the bobbins which are, of course, controlled in their arrangement by the skewers.

Suction units 49 are disposed outwardly of and near each upper and lower inclined pair of bobbins, the suction unit ybeing arranged above the upper pair of bobbins and below the lower pair of bobbins. Each suction unit includes a vertically inclined pipe 50, disposed near and between a pair of skewers 43, and parallel therewith. The inner end of the pipe 50, Figure 2, has screw threaded engagement within a sleeve 5I, rigidly mounted upon the outer face of the side I2 by welding or the like. The inner end of the pipe I2 is open and has communication with the tank Il, while its outer end is closed by a cap 52. Pivotally mounted upon each pipe 50 are collars 53 and 54. F18- tegral therewith, the collar 53 having an opening 5l leading into an opening 51 formed in the pipe 50. The collar 54 has an opening. 56 leading into an opening 53 formed in the pipe 50. The collars 53 and 54 have their ends screw threaded for engagement with screw threaded glands,

holding packing 6I. Arranged between the inner glands 60 is a spacing ring 62, andl stop rings 63 surround the pipe 50 and are clamped thereto by set screws 64 or the like. The glands and the packing form a vacuum tight Joint between the sleeves'63 and 54 and the pipe 50. These sleeves have Irictional engagement with the pipe 50, so that they may be turned upon. the pipe, but the sleeves will remain in .the adjusted position, unless manually moved therefrom. Slidably mounted upon the outer end or each tube 55 is a sleeve 65, the inner end of which is screw 'threaded for engagement with a screw threaded gland 66, having packing 61. The gland and packing form a vacuum tight ioint between the radial tube 55 and the sleeve 65, which ls adjustable longi tudinally upon the tube 55 and may also turn thereon. Thel frictional engagement between these parts is such that the sleeve 65 will remain in the adjusted position until manually moved therefrom. Each sleeve 65 carries an elongated nozzle 68, having an'inlet opening 69. opening 69 extends for` the entire length of the wound roving upon the bobbin. If desired, I may apply adjustable caps 10 upon the ends of the openings 69, so that the uncovered portions of these openings will correspond exactly to. the wound portion of the roving next to the opening 69.

The nozzles 68 are arranged in close relation to the wound roving of each pair of bobbins, and substantially contact therewith. The diameter of each individual cylinder of wound roving may vary, and such diameter decreases as the roving is unwound' therefrom. In order to obtain the desired suction action, the nozzle is swung closer to the bobbin, to bring its opening 69 close to the roving. The sleeve 65 may be longitudinally adjusted upon the radial tube 55, so that the nozzle will be retained in alignment with the diameter of the wound roving. It is thus seen that a suction nozzle is provided for each roving wound bobbin, which nozzle is adjustable, for the' reasons stated. Each pair of nozzles is carried by the inclined pipe, which leads to the interior of the tank. I have shown each tank as equipped with six of these inclined pipes. Suction is transmitted to each tank through the pipe 36, connected with the common suction pipe 36'. The lint and dirt removed from the several roving bobbins of each tank group is drawn into the tank. The large particles of lint or dirt accumulate upon the screen-partition, while the finer particles accumulate upon the screen 35. The screen-partition and screen 35 and associated elements are removable for cleansing purposes.

It is to be understood that the forml of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in' the shape, size and arrangements of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims. While I have shown the skewers and suction elements mounted upon one side i2 only of the tank I I, for the purpose of illustration, it is to be understood that these elements may be mounted upon both sides 0I the tank.
